  What protocols does the ip proxy software support? Is there a difference? Many people should be familiar with the proxy IP. In fact, there are still some protocols when implementing ip proxy software, but you must know which protocols are supported.

What protocols does the proxy IP support? What are the differences

  What protocols does the ip proxy software support?

  1.HTTP

  Hypertext Transfer Protocol (HTTP) is the most widely used network protocol on the Internet. All WWW documents must comply with this standard.

  2.HTTPS

  A more secure hypertext transfer protocol. That is, the SSL layer is added under HTTP. The security foundation of HTTPS is SSL, so SSL is required for the details of encryption.

  3.SOCKS4 and SOCKS5

  SOCKS proxy is divided into SOCKS4 and SOCKS5

  SOCKS5 is a proxy protocol, which plays an intermediary role between the front-end machine and the server machine that use the TCP/IP protocol to communicate, so that the front-end machine in the intranet can access the server in the Internet network, or make the communication more secure.

  But the difference is that SOCKS4 proxy only supports TCP protocol (that is, transmission control protocol), while SOCKS5 proxy supports both TCP protocol and UDP protocol (that is, user data packet protocol), as well as various authentication mechanisms, server-side domain name resolution, etc. .

  SOCKS5 that SOCK4 can do are available, but SOCK4 that SOCKS5 can do may not.
